La prise existante 18 est munie sur sa face avant de deux à cinq
crans suivant le gaz et est munie d'un clapet 13. Elle est montée
sur une douille à braser 24 (figure 5) logée dans le mur et raccor dée au réseau de distribution 25.The existing socket 18 is provided on its front face with two to five
notches according to the gas and is provided with a valve 13. It is mounted
on a brazing socket 24 (Figure 5) housed in the wall and connected to the distribution network 25.

Le dispositif de transformation ou d'adaptation selon l'invention
est formé par une douille monobloc 8 dont la face arrière est munie de deux à cinq tétons 4 coopérant, au montage, avec les crans
9 de la prise existante 18. La face avant 1 de la douille 8 est
fermée par un obturateur vissé 12 et comporte deux à cinq crans la
téraux 2 de largeur et de position convenables pour l'application voulue, et autant de rainures latérales 11 munies d'un cran de ver touillage pour un appareil ou une prise à brancher.The transformation or adaptation device according to the invention
is formed by a single-piece socket 8, the rear face of which is provided with two to five pins 4 cooperating, during assembly, with the notches
9 of the existing socket 18. The front face 1 of the socket 8 is
closed by a screwed shutter 12 and has two to five notches the
terals 2 of width and position suitable for the desired application, and as many lateral grooves 11 provided with a notch of worm for a device or a plug to be connected.

La douille 8 contient un clapet 5 rappelé par ressort, dont l'ex
trémité arrière traverse la face arrière 3 de la douille 8 pour venir en contact avec l'extrémité avant du clapet 13 de la prise existante 18. Le clapet 5 a un diamètre correspondant au fluide médical amené par le réseau 25. La face arrière 3 de la douille 8 comporte en outre une collerette 6 venant en appui sur un joint d'étanchéité 16 d'une bague vissée sur la prise existante 18.The socket 8 contains a valve 5 recalled by spring, the ex
rear end crosses the rear face 3 of the socket 8 to come into contact with the front end of the valve 13 of the existing socket 18. The valve 5 has a diameter corresponding to the medical fluid supplied by the network 25. The rear face 3 of the bush 8 further comprises a collar 6 bearing on a seal 16 of a ring screwed onto the existing socket 18.

La douille 8 porte en outre une vis radiale 7 qui, en venant se loger dans un cran 9 de la prise existante 18, immobilisera la douille 8 par rapport à cette prise 18.The socket 8 also carries a radial screw 7 which, by being housed in a notch 9 of the existing socket 18, will immobilize the socket 8 relative to this socket 18.

Lorsque l'ensemble qui vient d'être décrit n'est pas utilisé, les clapets 5 et 13 sont fermés. Lorsqu'une fiche ou un appareil est raccordé sur la face avant 1 de la douille 8, le clapet 5 pousse
le clapet 13 en libérant le gaz. On obtient ai#nsi un ensemble à double clapet, sans démontage, ni modification, ni coupure d'alimentation de la prise existante 18. When the assembly which has just been described is not used, the valves 5 and 13 are closed. When a plug or device is connected to the front face 1 of the socket 8, the valve 5 pushes
the valve 13 by releasing the gas. We obtain ai # nsi a double valve assembly, without disassembly, modification, or power cut of the existing outlet 18.

Un étrier 22 est maintenu en position contre le mur par un écrou 21 vissé sur la périphérie de la prise existante 8 et porte un boîtier 23. Un couvercle 19 fermant la face avant du boîtier 23 est maintenu et fixé par un écrou 20 vissé sur la douille 8. A bracket 22 is held in position against the wall by a nut 21 screwed onto the periphery of the existing socket 8 and carries a housing 23. A cover 19 closing the front face of the housing 23 is maintained and fixed by a nut 20 screwed onto the socket 8.

En cas d'incident sur la douille 8, il est toujours possible de la démonter et de raccorder provisoirement l'appareil sur la prise existante 18.In the event of an incident on the socket 8, it is always possible to dismantle it and temporarily connect the device to the existing socket 18.

La douille 8 peut être réalisée avec un systeme-de raccordement à une douille existante autre que les tétons 4 coopérant avec les crans 9, selon la forme de la prise existante.The socket 8 can be produced with a system of connection to an existing socket other than the pins 4 cooperating with the notches 9, depending on the shape of the existing socket.

Il est également possible de réaliser une douille 18 comportant elle-même un double clapet. It is also possible to produce a socket 18 itself comprising a double valve.
